Description

Fastening parts and seals for partition elements of a multi-part partition

The invention relates to a dividing wall for a column, in particular a packing and / or tray column, which carries out separations and / or chemical reactions and which has at least two dividing wall elements which are arranged one above the other and / or next to one another in the same plane and which have at least one plug-in and / or Clamping connection are interconnected, with a sealing profile arranged between the inner column wall and the end face of the partition wall elements facing the inner column wall and a fastening device for the partition wall on the inner column wall.

The international patent application WO 99/01193 discloses a dividing wall for columns which carries out separations and / or chemical reactions. The partition consists of several partition elements arranged one above the other and / or next to one another in the same plane. The dividing wall elements are arranged on column trays, horizontally extending plates or grids. These are in turn attached to support rings which are arranged on the inner wall of the column. A disadvantage of this prior art is that column trays, horizontally extending plates or grids can only be arranged on the predetermined support rings on the inner wall of the column. The support rings are usually welded firmly to the inner wall of the column, so that the support rings can only be moved with great effort. This means that the distance between column trays, horizontally extending plates or grids, between which packings can be inserted, is not variable.

Another disadvantage of the above The patent application is that leaks can occur between two partition elements. Leakages can also occur in the case of partition elements which are connected to one another by means of clamping and / or plug connections, since errors can occur in the manufacture of the clamping and / or plug connections. With a certain play in the clamp or plug connections, there are leaks or pressure losses.

The object of the invention is to improve a partition of the type mentioned in such a way that, in a structurally simple and inexpensive manner, independent of support rings, column internals and / or column trays fixedly attached to the column inner wall, can be introduced at any point of the column. Furthermore, it is an object of the invention to easily and inexpensively the spaces between the individual partition elements, i.e. to permanently and securely seal the clamp and / or plug connections.

According to the invention, these objects are achieved in that the top and / or lateral fastening parts of the dividing wall carry internals of the column and / or column bottoms or seals, in particular sealing cords, are arranged in the spaces between the plug-in and / or clamping connections of the dividing wall elements.

The fact that the partition itself carries column internals makes it very variable in a structurally simple and inexpensive manner Possibility created to add column internals, such as column trays and / or packs, to any position in the column. The insertion of the column internals is then independent of support rings that are attached to the inner wall of the column. This is created by fastening parts arranged on the side of the partition wall elements. These fastening parts can be arranged at any point, in particular on the sides, on the partition elements. In this way, any desired installation height for column internals can be easily achieved. Partition wall elements can optionally be used which have fastening elements in the lower, middle or upper lateral area. Depending on the installation height, partition elements with fastening parts arranged at different heights on the partition elements can be used. As a result, the desired installation position of the individual column internals, such as, for example, mass transfer trays, can be achieved when the partition is being assembled.

It is expedient if the lateral fastening parts, in particular non-positively and / or cohesively, are fastened to the partition wall elements. This creates a permanently secure hold of the fasteners on the partition elements. The fastening parts can either be arranged only on one side of the partition elements or on both sides of the partition elements.

The fastening parts ideally represent profiles, in particular rectangular profiles, which run perpendicular to the inner wall of the column. The tops of the fasteners, which are particularly horizontal, serve as a support for column internals. The fastening parts can have different lengths. Depending on the installation positions of the partition elements, the fastening parts are shorter or longer. A dividing wall element which is close to the inner wall of the column has, for example, a shorter fastening part than a dividing wall element which is arranged centrally in the dividing wall. It is not imperative that the tops of the profiles run horizontally. A further advantageous embodiment of the invention provides that the fastening parts each have at least one holding device, in particular a bore, for securely receiving the column internals. The column internals are releasably attached to this mounting device, so that a secure and firm fit of the column internals is ensured. The mounting device can be designed in various ways. A simple solution is provided by holes in the fastening parts. One or more holes can optionally be arranged in the fastening parts. Ideally, these run vertically or horizontally through the profile. The column internals can be fastened to the fastening parts by simple screw connections. The holding devices can also have plug-in or clamp connections which receive the corresponding column internals in a form-fitting manner. Snap or clip connections are a simple connection.

It is also expedient if the dividing wall elements each have at least one holding device, in particular a bore, for receiving the fastening parts or the column internals.

It is expedient if the end faces of the partition wall elements according to the invention facing the column inner wall are connected to the sealing profile by a plug and / or clamp connection. In this way, a secure and firm connection between the partition elements and the sealing profile can be created in a simple manner. The plug and / or clamp connection to the sealing profile is the same plug and / or clamp connection as between the partition elements. Alternatively, the end face of the partition wall elements facing the inner column wall can be connected to the sealing profile by a material connection. A material connection, such as a welded connection, creates a permanently firm and tight connection between the sealing profile and the partition element. A plug-in and / or clamp connection has the advantage that the dividing wall elements can easily be detached from the inner column wall or from the sealing profile on the inner column wall. An advantageous embodiment of the fastening device provides that the sealing profile is arranged in one plane with the partition elements. It is particularly advantageous if the sealing profile has the same thickness as the partition elements. The clamping profiles overlap the partition elements and the sealing profile on both sides and thus clamp the sealing profile and partition elements between them. Because the sealing profile is fixedly attached to the inner column wall or to projections which are arranged on the inner column wall, the dividing wall elements can be fixedly attached to the sealing profile.

It is also of great advantage if the sealing profile and the partition elements can be pressed apart by a pressure element. This means that the space between the end face of the dividing wall elements and the sealing profile can be widened in the horizontal direction during or after the attachment of the clamping profiles of the fastening device, so that on the one hand the sealing profile is pressed firmly against the inner wall of the column and on the other hand the dividing wall elements are pressed together. This creates a secure seal between the partition elements and a secure seal between the sealing profile and the inner wall of the column. This gives the partition wall, which consists of several partition elements, more stability and tightness. The pressure element can be a type of wedge, which is subsequently inserted into the space from above. After a row of dividing wall elements has been put together, they are pushed together by introducing the pressure element into one space or into both spaces, so that they are arranged in the column in an absolutely firm and resilient manner. After the pressure element has been introduced and the partition elements of a row have been pressed together, the next row of partition elements lying above it is pushed onto the lower row and pushed together again by means of pressure elements. The pressure element can also be introduced horizontally between two partition elements, ie between two partition elements lying one above the other in one plane. A device consisting of two elongated profiles is also conceivable, one profile of which rests on the sealing profile and the other on the partition element. The two profiles can be pressed apart, for example, by a sliding device. The displacement device consists, for example, of two displaceable rods, a gear mechanism through which the rods can be displaced and a lever through which the gear mechanism can be actuated.

The partition wall elements and the sealing profile can have bores or holes, in particular elongated holes, in order to be connected to one another in a force-locking manner. After the space has been pressed apart by the pressure element or after the partition elements have been pressed together, the partition elements and the sealing profile can additionally be connected securely and tightly by screw connections.

A further advantageous embodiment of the partition wall provides that the partition wall elements have handle devices to facilitate alignment or assembly. This makes it easier to connect the partition elements. The handle devices are either arranged directly on the sides of the partition elements or on the fastening parts. The fasteners can also perform the function of handle devices themselves.

In order to seal the interstices of the individual partition elements, ie the clamping and / or plug connections permanently and securely in a simple and inexpensive manner, it is advantageous to arrange seals, in particular sealing cords, in the interstices of the plug and / or clamping connections of the partition elements. This additionally ensures the tightness between the partition elements. The seals are, in particular, sealing cords which are introduced into the clamping or plug connections when the individual partition elements are assembled. The sealing cords ideally run in one piece over the entire height of the partition elements. But it is also conceivable that between everyone individual clamping or plug-in connection, a sealing cord running over the entire length of the clamping or plug-in connections is introduced. The seals can also be arranged in grooves on the end faces of the partition elements. By pressing the partition wall elements together, the sealing cords are compressed so that they ensure an absolutely tight connection between two partition wall elements.

It is also advantageous if seals are arranged between the sealing profile and the end face of the partition wall elements facing the sealing profile. This also creates an absolutely tight connection at the connection between the partition and the sealing profile.

Furthermore, a sealing compound can be introduced in the spaces between the plug-in and / or clamping connections of the partition elements and / or between the sealing profile and the side of the partition elements facing the sealing profile. In particular, a self-curing sealant, which is introduced into the spaces between the plug and / or clamp connections, creates a tight connection.

Further details and advantages of the subject matter of the invention result from the following description, the associated drawings, in which preferred exemplary embodiments are shown with the necessary details. Show it:

1 and 2, one or two partition elements (3) with plug and / or clamp connections (4) are shown on their side surfaces. A fastening part (7) is arranged on the sides of the partition element (3). The fastening part (7) is welded to the partition element (3) or detachably fastened in a non-positive or positive manner. The fastening parts (7) can be arranged at any position of the partition element (3). For example, they can also be attached to the plug or clamp connections (4). The fastening parts (7) can be arranged on both sides of the partition. The size of the fastening parts (7) is variable. Depending on the installation position of the partition element (3) in the column (2), the size of the fastening parts (7) can be selected. The fastening parts (7) or the upper side (13) of the partition (1) can carry column internals (17), such as mass transfer trays or packings. The dividing wall (1) is so firmly arranged in the column (2) that additional weights can be applied to it through column internals (17). In addition, the fastening parts (7) can have holding devices (22) to which the column internals (17) can be fastened. The mounting devices (22) can be plug or clamp connections. Another simple variant is represented by bores (22) to which the column internals (17) can be detachably fastened with the aid of screw connections. It is also possible for the column internals (17) to rest positively on the fastening parts (7) or on the upper side (13) of the partition (1). Adequate stability is then created by the weight and shape of the column internals (17). Fig. 3 shows a vertical section through part of a column (2), with a partition (1) consisting of several pluggable or clampable partition elements (3), and a fastening device (6) for the partition (1) on the inner column wall (5). The fastening device (6) is formed in this example by the sealing profile (9), which is firmly attached to the inner wall of the column (5), for example by a welded connection. The dividing wall (1) divides the column (2) into two halves, the dividing wall (1) separating the inflow into the column (2) from the outflow from the column. The partition (1) is tightly attached to the sealing profile (9) on both sides of the inner column wall (5). Fastening parts (7) with mounting devices (22) are arranged on some partition elements (3). As a rule, several partition wall elements (3) with fastening parts (7) are arranged in one plane, so that a good contact surface or holder for the column internals (17) is created. The column internals (17) can also be additional support elements, as a further mounting option for trays or similar column internals.

Some partition elements (3) have handle devices (12). These serve for better assembly and disassembly of the partition. When assembling the partition (1), force can be exerted on the individual partition elements (3) better via the handle devices (12) in order to align them with one another.

The fastening device (6), in this exemplary embodiment formed by a sealing profile (9) welded to the inner column wall (5), and the dividing wall elements (3) can have bores or holes, in particular elongated holes (15, 14), through which they are non-positively connected to one another can be connected. The bores or holes (14) are arranged in particular on the clamping profiles (10, 11) of the partition elements (3).

Fig. 4 shows a partition element (3) with a fastening part (7) which is arranged on the side of the partition element (3). The handle device (12) is attached to the fastening part (7). In Fig. 5 the handle device (12) is arranged directly on the partition element (3). The handle device (12) consists of a simple profile which is attached to the partition element (3). Ideally, handle devices (12) are attached to both sides of the partition element. Fig. 6 shows a top view of a partition (1) consisting of several partition elements (3) with fastening parts (7) and handle devices (12) on the fastening parts (7). Holding devices (22) are also located on the fastening parts (7). In this example, elongated holes, the axes of which run parallel to the partition (1), are shown as holding devices (22). Depending on the column internals (17), the holes can also have a different course.

In order to obtain an absolutely tight connection after the individual partition elements (3) have been plugged together, a seal (19), in particular in the form of a sealing cord (16) or a sealing compound (21), is inserted into the spaces (18) of the plug-in and / or clamp connections (4) inserted. After the partition wall elements (3) have been plugged or clamped together, the seal (19) is elastically deformed and thus forms an absolutely tight connection between the partition wall elements (3). 6 shows a non-deformed seal (19) or sealing cord (16) which lies in the intermediate space (18) in the upper region. In the lower part of the binding, a seal (19) or sealing cord (16) deformed by the two joined partition elements (3) is shown. A sealing compound (21) can also be inserted on the bottom of the intermediate spaces (18), which deforms and hardens after the partition wall elements (3) have been joined, thus creating a tight connection.

Fig. 7 again illustrates how the seal (19) or the sealing cord (16) lies in the space (18). Another variant of the mounting device (22) is shown in this figure. The partition element (3) has a holding device (22), in this case a bore, to which column internals (17) can be attached. The column internals (17) can optionally be fastened directly to the dividing wall (3) or to a fastening part (7) attached to the dividing wall (3). Fig. 8 shows a horizontal section through a column (2) with a partition (1) consisting of several partition elements (3). Fastening parts (7) are attached to every second partition element (3) on both sides. Either the column internals (17) can be arranged directly on these or on these, or further support elements on which the column internals (17) are arranged. An intermediate piece (8), in particular a pressure element, is introduced between the sealing profile (9) and the outer partition element (3). The intermediate piece (8) can be a wedge, for example, which is introduced into this intermediate space from above. This inserted intermediate piece (8) ensures that the partition (1) is absolutely secure. The dividing wall elements (3) are pressed firmly and tightly against one another by the introduction of the intermediate piece, so that the dividing wall (1) achieves sufficient stability to easily carry the further column internals (17). To support the partition (1) can also be attached to a support ring (23).
